USB_SSTXP_DN2

A11

USB SuperSpeed transmitter differential pair (positive). Note: When routing, it is

permissible to swap the positive and negative signals in Port 2 SSTX differential

pair.

USB_SSTXN_DN2

B10

USB SuperSpeed transmitter differential pair (negative). Note: When routing, it is

permissible to swap the positive and negative signals in Port 2 SSTX differential

pair.

USB_SSRXP_DN2

USB SuperSpeed receiver differential pair (positive). Note: When routing, it is

permissible to swap the positive and negative signals in Port 2 SSRX differential

pair.

USB_SSRXN_DN2

A10

USB SuperSpeed receiver differential pair (negative). Note: When routing, it is

permissible to swap the positive and negative signals in Port 2 SSRX differential

pair.

USB_DP_DN2

B12

I/O

USB High-speed differential transceiver (positive).

USB_DM_DN2

A13

I/O

USB High-speed differential transceiver (negative).

PWRON2#

B34

O PD

USB DS Port 2 Power On Control for Downstream Power. The terminal is used

for control of the downstream power switch. If the PWRON_POLARITY bit is set

to 1, this pin is active high and the internal pull-down is disabled. This pin may be

at low impedance when power rails are removed.

OVERCUR2#

A37

I PU

USB DS Port 2 Overcurrent Detection. 0: overcurrent detected; 1: overcurrent

not detected

USB_SSTXP_DN3

—

B28

permissible to swap the positive and negative signals in Port 3 SSTX differential

pair.

USB_SSTXN_DN3

—

A30

USB SuperSpeed transmitter differential pair (negative). Note: When routing, it is

permissible to swap the positive and negative signals in Port 3 SSTX differential

pair.

USB_SSRXP_DN3

—

B27

USB SuperSpeed receiver differential pair (positive). Note: When routing, it is

permissible to swap the positive and negative signals in Port 3 SSRX differential

pair.

USB_SSRXN_DN3

—

A29

USB SuperSpeed receiver differential pair (negative). Note: When routing, it is

permissible to swap the positive and negative signals in Port 3 SSRX differential

pair.

USB_DP_DN3

permissible to swap the positive and negative signals in Port 4 SSTX differential

pair.

USB_SSRXP_DN4

—

USB SuperSpeed receiver differential pair (positive). Note: When routing, it is

permissible to swap the positive and negative signals in Port 4 SSRX differential

pair.

USB_SSRXN_DN4

—

USB SuperSpeed receiver differential pair (negative). Note: When routing, it is

permissible to swap the positive and negative signals in Port 4 SSRX differential

pair.

USB_DP_DN4
